Is a locality name. The first land grant of Cullen Bullen, (2000ac), was taken up by Robert Venour Dulhunty. His brother Lawrence Vance Dulhunty also took a large grant of land nearby. Robert Dulhunty was at one stage Commissioner of Disputed Land Claims in Queensland. Robert's son, Lawrence Joseph Edward Dulhunty, moved to Queensland, where he held extensive properties and was a well-respected and influential person. Dulhunty Plains and Dulhunty River were named after his family. The Dulhuntys took an interest in Aboriginal names of the Tambo area. An Aboriginal name for water and drink in the Norman River area was "baal". Locally, Baal Bone Gap is the only easy accessible means through the cliff line to the headwaters of the Baal Bone Creek and further south to the headwaters of the Coxs River. The coining of the word, "bone" as in "pointing the bone" adds direction via this gap. Ref: Indigenous word lists compiled by Smyth and Curr.
